Each side of geogrid is not less than 3 meters, what does it mean?
Design requirements obviously not for this purpose, I consider is not a few geogrid lap width than the roadbed width of three meters, and then backfill roadbed soil after 60 or 80 cm and then the two sides of the geogrid back.
If each side is folded three meters, then it is folded
At present, the largest width of single geogrid is 6 meters
